Hey All, I just picked up a 2012 EC Limited. I wanted opinions on: Doing (SE Street Perf) slip-ons first and waiting for the Air/Tune later? Any savings in doing it in one step? Obviously I just dropped the down payment and I'm not in a real rush to drop $1500 right away but the stock sound is just way too tame. Also, any thoughts on a path to achieving 100/100? Thanks - Great Forum.
